Correlation coefficients of the annual probability levels of LMI with time (linked black dots) and GMSST (linked orange dots). The annual probability level means the annual variation of the cumulative proportion at each threshold LMI. Observations come from a JMA and b JTWC, respectively. Ninety-five percent confidence intervals are shaded in gray and orange colors for time and GMSST, for each. The average of the annual probability levels is labeled on the right ordinate
